function

`scipy.interpolate._polyint:BarycentricInterpolator.derivative`

source: /scipy/interpolate/_polyint.py :864

Signature

def derivative ( self , x , der = 1 )

Summary

Evaluate a single derivative of the polynomial at the point x.

Parameters

x : array_like: Point or points at which to evaluate the derivatives
der : integer, optional: Which derivative to evaluate (default: first derivative). This number includes the function value as 0th derivative.

Returns

d : ndarray: Derivative interpolated at the x-points. Shape of d is determined by replacing the interpolation axis in the original array with the shape of x.
